Auto safety –
Owner complained to family about the dangerous bug — but may not have told Tesla.
Forensic data also suggests one reason Huang might not have been paying attention to the road in the final seconds before his death: he was in the habit of playing a game called Three Kingdoms in his car while driving to work. Logs from his Apple-provided iPhone showed that he used the app during his morning commute every day the week of his fatal Friday crash. However, those logs don’t provide enough information to say if he was interacting with the game in the final seconds before his death.
The NTSB board is scheduled to hold a hearing on the Huang crash next week. At that point, it’s expected to formally determine the cause of the crash and make safety recommendations. Based on the documents released so far, it seems that both Tesla and California officials could get some of the blame. Huang’s vehicle had the same glitch in the same spot before
Ever since Huang’s death, his wife and brother have insisted that this wasn’t the first time Huang’s Model X had experienced this kind of problem. The new documents offer clear confirmation of this claim. On at least two prior occasions, Huang’s Model X tried to steer into the concrete barrier at exactly the same spot along highway . Each time, Huang noticed the mistake and grabbed the wheel, steering it back into the correct lane.
The NTSB’s primary evidence is log data that is stored to an SD Card inside every Model X. This data records second-by -second changes in the vehicle’s steering-wheel position, velocity, and other variables. NTSB examined log data from a month of Huang’s morning commutes and found two days — February and March – when the vehicle drifted toward the lane divider that would kill him days later. In each case, logs show Huang applying torque to the steering wheel and guiding the vehicle back into its proper lane.
However, the NTSB was not able to confirm another claim by the family — one that could prove important in their lawsuit against the electric carmaker. Walter Huang’s wife and brother say that he alerted a Tesla representative about Autopilot’s steering problem during a visit to a Tesla service center weeks before his death. Records show that Huang did visit a Tesla service center to address a problem with the vehicle’s falcon-wing doors. A defective sensor had caused one of the doors to bump into the garage above the vehicle, causing minor paint damage.
The family says Huang told Tesla about the problem with Autopilot during that same visit. But Tesla has no record of this. Tesla records do show Huang visiting a Tesla shop about the door issues. And Tesla’s service logs show that Huang reported an “issue with GPS / Navigation causing cruise control to not function and alert ‘maps not loaded’ to appear.”
Deadly car crashes often have multiple causes, and that was certainly the case here. Deficiencies in Tesla’s software surely contributed to Huang’s death, as did Huang’s failure to pay attention. But Huang might also still be alive today if California officials had been more proactive about road maintenance.
